The Dallas Mavericks expect to agree to a three-year, $33 million contract extension with center Dwight Powell in the opening stages of free agency Sunday evening, sources confirmed to ESPN.
Powell recently exercised his $10.3 million player option for next season with the plan to work out an extension to stay in Dallas long term.
The Mavs consider Powell, 27, a key member of the supporting cast for their pair of young stars, Rookie of the Year Luka Doncic and Kristaps Porzingis, who is expected to formally agree Sunday to the five-year, $158 million maximum contract that has been planned since Dallas traded for him midseason.
